On-base Plus Slugging (OPS) is a critical statistic in baseball, offering a comprehensive snapshot of a player’s overall offensive performance. Unlike traditional metrics that focus on singular aspects of play, OPS combines on-base percentage (OBP) and slugging percentage (SLG) to provide a fuller understanding of a player’s ability to get on base and hit for power. This metric has become a favored tool among analysts, coaches, and fans for its effectiveness in evaluating players’ contributions beyond conventional statistics.
Formula of OPS Calculator Baseball
The calculation of OPS is straightforward but requires understanding its components:
OPS = OBP + SLG
Breaking down the components:
- OPS: On-base Plus Slugging, the metric we calculate.
- OBP: On-base Percentage, a measure of how often a player gets on base.
- SLG: Slugging Percentage, a measure of batting productivity.
Formulas for OBP and SLG are as follows:
OBP = (H + BB + HBP) / (AB + BB + HBP + SF)
Where:
- H: Hits
- BB: Bases on Balls (Walks)
- HBP: Hit By Pitch
- AB: At Bats
- SF: Sacrifice Flies
SLG = (1B + (2B * 2) + (3B * 3) + (HR * 4)) / AB
Where:
- 1B: Singles
- 2B: Doubles
- 3B: Triples
- HR: Home Runs

Most Common FAQs
A high OPS indicates that a player is effective both at getting on base and in hitting for power, making them a valuable offensive asset to their team.
While batting average focuses solely on hits, OPS provides a more comprehensive view by incorporating on-base ability and power hitting. This makes OPS a more holistic measure of a player’s offensive value.
Teams and analysts use OPS to assess players’ offensive value, compare players across different positions, and make strategic decisions about lineups and player development.
